While cryonics isn't proven science yet, we have frozen dogs, pigs, and other animals and revived them after a few days. I'm sorry, you are mistaken. The largest reversibly-cryopreserved chunk of mammal so far has been a rabbit kidney. The kidney was cryopreserved, re-warmed, and transplanted back into the rabbit. The untreated kidney was removed. The rabbit recovered and survived until the researchers euthanized it for autopsy 6 weeks later. Autopsy showed some areas where the cryoprotectant hadn't reached, so the kidney wasn't perfectly healthy.
